It's difficult for me to not let people guilt/control me with money

Any tips? Books I could read? Necessary mindset shift? Insight into why I might be prone to this?

Examples from my past because I want to vent now (can be ignored):

Wanted x amount of tokens to show my pussy. A guy talked me down because my cam quality was "poor" so it wasn't worth that amount in the camming industry, he said. I bought it because I was new. Felt guilty setting goals at all for years, was afraid people would straight up scold and ridicule me if I put a price on anything.

Once I got over that I started getting whales--the guys who spend hundreds every stream or maybe even thousands every once in a while. 2 people have admitted to me that they went into debt and pretended to be rich in my room for attention and to out tip other people. I suspect 1 other is in the same boat but hasn't told me yet. He fits the pattern I've learned. They were in love with me or something. I remember I would feel immense pressure to bend over backwards for these people, sharing my phone number and access to personal details about myself. I should have known they were spending money they didnt have because they'd tip thousands, dip for a few weeks (have to wait to get paid again or save up you know?), ask for exclusivity, maybe point out how much they'd spent. I often had to pretend to like them, because they weren't talented or charming or anything. It came out that one was a 50 year old virgin who was just sending me online gambling winnings, and honestly his personality was just so depressing.
